According to the annals of Shalmaneser I, discovered at Assur, it was an ancient Assyrian city on the Tigris and traditional capital of Assyria, near the modern city of Al-Shirqat in Iraq. He destroyed the fortress of Arinnu, "the dust of which he brought to Assur."{{cite book|url=https://books.google.com/books?id=aGk6AQAAMAAJ&pg=RA1-PA798&dq=%22Arinnu%22+-wikipedia&hl=en&newbks=1&newbks_redir=0&source=|title=Encyclopedia Britannica: Shalmaneser|page=798|year=1911|access-date=June 10, 2025}}

After it was "razed to the ground," the Assyrians re-built their capital city.

It was placed under siege a second time by Tiglath-pileser I, but the city surrendered voluntarily that time and was spared destruction after they promised tribute (bribes and taxes).

It was later controlled by Shubria.
